SPREAIJER FOR DRY MATERIALS.

Specification of Letters Patent.

Patented Nov. 21, 1916.

To all whom it may concern.'

Be it known that we, JOSHUA R. KING and WILLIAM O. KING, citizens of the United States, residing, respectively, at New Haven, in the county of Oswego and State of New York, and Sidney, in the county of Delaware and State of New York, haveinvented a new and useful Spreader for Dry Materials, of which the following is a speciiication. V

The present invention relates to an improved machine for distributing and spreading dry materials, such as pulverized and granular materials, including crushed stone, lime, and other fertilizers, and the like.

An object of this invention is to provide a spreader of this character which' is of simple and light construction and provided with a revolving drum-shapedbody having adjustable outlets therethrough to distribute the material in a layer of the desired thickness as the body revolves; and which has means for adjusting these outlets without removing the material from the body, and vwithout the necessity of overcoming` the pressure of the vweight of the material.

Another object of the invention is to pro; vide a spreader of'this nature with means for insuring the even distribution of the material entirely across the path of the machine, whether the machine is on level land, or whether. it is traveling' along the side of a hill.

A still further object of the invention is to provide an improved adjusting mechanism which is adapted to revolve with the body of the machine, and which simultaneously adjusts a plurality of outlets and securely holds all of the same when adjusted, to thus uniformly feed or distribute the material from the machine.

Other objects and advantages of this invention will be brought out in the following specific disclosure of the present preferred embodiment of the invention, the same being illustrated in the accompanying drawings, whereinl Figure J, is' a top plan view of a spreader constructed according to this invention. Fig. 2 is a longitudinal central sectional view, taken vertically through the machine, the shutters being closed. Fig. 3 is a transverse central sectional view, taken through the machine. Fig. 4, is an enlarged, fragmentary sectionalview, through the central Adesignates an axle upon the opposite ends of which are mounted traction wheels 11, one of which at least is fixed to the axle 10, as by a key 12, shown in Figs. l and 3.

The body of the machine is in the form of a drum or cylinder, and comprises the opposite ends or heads 13, a plurality of circumferentially spaced apart slats 14 and interposed adjustable shutters 15. The heads 13 are in the form of disks having central openings therethrough for the reception of the axle 10 and having clamping plates 16 secured, by bolts 17, or the like, against the outer faces of the heads 13 and about the axle 10. Bushings 18 are carried in the clamping plates 16 and have flanges 19 counter-sunk in the inner faces of the plates 16 and adapted to be securely clamped from turning between the heads 13 and the plates 16. The bushings 18 bind on the aXle 10, to turn therewith, so as to turn the drumshaped body with the axle.

The outer ends of the bushings 18 are mounted to turn in side bars 20 which are enlarged and apertured intermediate their ends to receive the bushings 18 therethrough.

End bars 21 join the side bars 20 to provide therewith a substantially horizontal frame encircling the cylindrical body. A tongue 22 is carried on one end of the frame for drawing the machine. Spacing rings 23 are preferably interposed between the outer ends of the bushings 18 and the wheels 11 to space the latter from the side bars 20 of the frame.

Each slat 14 of the drum-shaped body comprises a fiat metal strip secured at its opposite ends to the peripheral edges of the heads 13, and having an outturned reinforcing flange 24 along one edge. The opposite edge of the strip 14 is offset inwardly from posite ends for engagement over the headed projections 27 to hingedly connect the shutters 15 to the slats 14. There is thus a shutter hinged on each slat. The slats 14 are counter-sunk in the peripheral. edges of the heads 13, so as to close the body at the edges of the heads.

The body is provided with a central partition 29, which divides the body into two compartments, so that should the body be tilted, the material will not collect in one end of the body, and thus be unequally distributed across the path of the machine, but will be held in the opposite ends and caused to pass out of the openings, between the slats and the outer ends of the shutters, entirely across the machine. The partition 29 is preferably fixed to the axle, as by a key 30, to further secure the body to the axle.

The body is provided in one side with a door or hinged cover adapted to be opened to place material in the lateral compartments in the body. This door comprises a plurality of slats 14 and shutters 15 of the same construction and arrangement as the remaining slats in the body, with the exception that these door slats 14 are secured upon a frame composed of a pair of opposed strips 43, of metal or the like, counter-sunk in the peripheries of the opposed heads 13, each strip being substantially of the same width as its supporting head 13. These strips 43 are located at one side of the body and conform to the recesses therein. The slats 14 of the door section are secured fiat against these frame strips, and the hinged slats lie flat against the frame strips when the slats are closed. The door is secured at its inner edge by hinges 31 to the adjacent slat 14, the hinges being secured to the two adjacent slats 14 and to the heads 13 beneath the opposite ends of the slats. The free edge of the door section of the body is held closed in any suitable manner, such as by a finger 32, (Fig. 2) hinged upon one of the slats 14 adjacent the free edge of the door section. It will be noted from the drawings that the door section terminates at its hinged and free edges in slats 14, and that the body wall of the device terminates in fixed slats 14, so as to provide a suitable hinge connection for the door, and also a suitable support for the fastener 32, which is adapted to hold the door closed. The shutters 15 are adapted to be swung, to more or less extent, outwardly from the outturned flanges 24 of the slats in order to increase or decrease the space therebetween and admit more or less of the contents of the body to pass outwardly through the openings. Adjusting and retaining means are provided for, these shutters 15, and are connected to a plurality of the same, so as to operate them simultaneously. The adj usting and holding devices are shown in the present instance as three in number, spaced substantially equi-distantly about the body, one of the devices being mounted on the door to control all of the shutters 15 carried thereby. Each one of these adjusting and holding devices comprises a rigid band or strip 33 connected at one end to one of the slats 14 by means of links, 34, and passing peripherally across the desired number of the shutters 15. The band 33 has a hinged connection with each of the outturned fianges 26, the connection being shownin the present instance as comprising a substantially U-shaped bolt 35 threaded at its extremities, engaging at its intermediate portion through the flange 26, and projecting outwardly through the band 33. Binding nuts 36 are threaded upon the outer ends of the U-bolt and are turned up against a clamping plate 37, which lies against the outer side of the band 33. A bracket plate 33,. in the form of an angle iron, has one flange thereof secured to a slat 14 lying intermediate the ends of the band 33. The outstanding flange of the bracket plate 38 has a slot 39 therethrough to receive and admit of the longitudinal and outward movements of the band 33. Fixed on the band 33 is an outstanding lug 40, spaced from the bracket plate 38 and provided with a vertically movable sleeve 41l in one side of which is swiveled the inner end of an adjusting screw 42.

To use the device, the finger 32 is turned out of engagement with the slat 14 on the outer end ofthe door. The door is now swung outwardly on the hinges 31. The body of the machine is so turned as to dispose the door at the top thereof. The material is now placed in preferably equal quantities in the end compartments or sections of the body. After the door is closed and it is desired to adjust the shutters 15 to regulate the amount of material distributed through the openings or slots in the body, the body is turned so as to bring the separate adjusting devices one-at a time tothe top of the body, sothat the respective shutters of the adjusting devices may be adjusted into the desired position without the necessity of overcoming the pressure of the weight of the material against the shutters 15 at the lower side of the body.

In adjusting-'the shutters 15, the screw 42 is turned so as to draw the lug 40 toward the bracket 38 or toward and into the position shown in Fig. 4l. The lug 4U moves the band 33 circumferentially around the body toward the bracket 38. The band 33 swings upon the links 3d and moves away from the adjacent side of the body.

The sleeve 41, carried by the lug 40, remains in alinement with the adjusting screw 42 as the lug 40 is free to slide outwardly in the sleeve. The sleeve 4l is cut away at its lower edge to receive the bore of the lug and admit a free adjustment of the lug and band within a wide range. Each one of the adjusting devices is of this construction and is operated in this manner. It is preferable to rotate the body as above described, so as to bring the shutter adjusting devices one at a time to the top of the body.

When the desired adjustment of the shutters 15 is had, the machine is moved along over the surface to rotate the drum-shaped body. This turning ofthe body tumbles and loosens the material therein and causes it to fall outwardly through the slots or openings between the shutters and the slats. The partition 29 in the body insures an even distribution of the material from end to end of the body when the body 1s hori- Zontal, and when it is tilted, as when being moved over the side of a hill.
